Magnetic pump overload
Thread Content
Our company has a Sanwa magnetic pump; after running smoothly for a few hours, it suddenly overloaded. No obvious defects were found upon disassembly. Does anyone know what could cause such a situation?
Could it be caused by suddenly high flow rates? You can try using the pump below
Is the power supply voltage stable? Have there been any changes in density or viscosity? Is the outlet pressure stable? Is there any contact rotation inside the pump? Are the motor bearings faulty? Is the motor’s cooling effect inadequate?
Overload is generally caused by excessive resistance; aside from issues with the motor and materials, it is necessary to check whether there are any abnormalities in the mechanical components. For example, whether the mouth ring or thrust ring is loose, etc.
It should be described in detail whether the current suddenly increases, whether the motor activates its overload protection mechanism, whether there are any sounds of damage coming from the bearings of the magnetic pump, and whether cavitation or vacuum formation occurs in the pump
There are many reasons for overload in Sanwa magnetic pumps; for specific issues, please contact Jiangsu Guanyu’s technical support at 152-9882-3905 for assistance
Overload; there were no issues when the pump was disassembled, it wasn’t damaged. I’ve never seen a magnetic pump like this before
